Answer:
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.

Answer:
69 grams, as SO2 is interacting with the burning of coal
Answer:
SO₄²⁻(aq) + Ba²⁺(aq) ⇒ BaSO₄(s)
Explanation:
Let's consider the molecular equation that occurs when aqueous solutions of ammonium sulfate and barium nitrate are mixed.
(NH₄)₂SO₄(aq) + Ba(NO₃)₂(aq) ⇒ BaSO₄(s) + 2 NH₄NO₃(aq)
The complete ionic equation includes all the ions and insoluble species.
2 NH₄⁺(aq) + SO₄²⁻(aq) + Ba²⁺(aq) + 2 NO₃⁻(aq) ⇒ BaSO₄(s) + 2 NH₄⁺(aq) + 2 NO₃⁻(aq)
The net ionic equation includes only the ions that participate in the reaction and the insoluble species.
SO₄²⁻(aq) + Ba²⁺(aq) ⇒ BaSO₄(s)
Answer:
Change in temperature = 74
Explanation:
The initial Temperature of the chicken is given as 0° C. Then the question states that the chicken is added to sous-vide cooker. And the final equilibrium temperature after cooking is given as 74°C. The equilibrium temperature means that the temperature of each component in the system, such as cooker and chicken is same, which is 74°C. So, we have:
Initial Temperature = 0
Final temperature = 74
Therefore, the change in temperature during cooking will be:
Change in Temperature = Final Temperature - Initial temperature
Change in Temperature = 74 - 0
<u>Change in temperature = 74</u>
